Abstract

The invention relates to a compound foamed plastic-wood composite material plate and a preparation method thereof. The preparation method comprises the following steps: adding polyvinyl chloride and dibasic lead phosphite into a stirring kettle, and evenly mixing at high temperature; adding wood powder, kaolin powder, accelerator, azobisformamide, calcium stearate and chlorinated polyethylene into the stirring kettle, heating, evenly mixing, and cooling; adding o-toluenesulfonhydrazide and dibutyl phthalate into the kettle, heating, evenly mixing, cooling, taking out the mixture, and granulating by extrusion; and after finishing the granulation, carrying out extrusion molding on the granules. The invention has the advantages of high manufacturing convenience, low cost, light weight, low brittleness, excellent ductility, excellent shock resistance, favorable surface tactile sensation, sound insulation, heat insulation, aging resistance, discoloring resistance and no buckling deformation, is convenient to mount and maintain, and can adsorb toxic gas; and the invention consumes less plastic, is environment-friendly and can be recycled. The invention can be used in office buildings, families and other occasions, and can be made into door plates, photo frames, picture frames, skirting plates, suspended pinch plates, suspended beams, pergolas and the like.

Description

technical field [0001] The invention relates to a plastic-wood composite material, in particular to a composite foamed plastic-wood composite material board and a preparation method thereof. Background technique [0002] Wood-plastic composite materials use hot-melt plastics, including polyethylene, polypropylene, polystyrene, etc., and their copolymers as adhesives, and use wood powder such as wood, crop straw, and crop shell powder as fillers. Composite materials formed by extrusion, compression or injection molding. Wood-plastic composite materials have the dual characteristics of wood and plastic: good mechanical properties, good secondary processability, no fear of moths, no mold, no moisture absorption, long service life and reusable use. However, compared with the base plastic, its mechanical properties such as toughness, impact strength and bending strength will still be reduced. As a wood substitute, its density is too high and its application fields are limited. ...
